A total of 12 mice are sent down a maze, one by one. From previous experience, it is believed that the probability a mouse turns right is 0.3. Suppose their turning pattern follows a binomial distribution. Use the PDF or the CDF command to help answer each of the following questions.

3. what is the probability that 5 or more turn right?

4.what is the probability that more than 5, but fewer than 9 turn right?

5.what is the probability that exactly 6 of the 12 mice turn left?
